TO ALL WHOM IT MAY CONCERN:

Be it known that we, WILLIAM P. Parson and JACOB R. MILLER, ot the city of Harrisburg, county of Dauphin, and State of Pennsylvania, have invented a nen1 and useful Improvement in Oil-Cups; and we hereby certify that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters of reference marked thereon.

The nature of o ur invention consists in the peculiar combination and arrangement of an adjustable spindle or plug with the shank or screw-stem of an cil-cup, substantially-as hereinafter set forth. In the drawings, making a. part of this specilication- 'Figure 1 is a perspective view of the oil-cup, and

-Figure 2 a vertical section of the same, showing the interior of the cup and position of the plug.

In figs. 1 and 2, A represents the oil-chamber, surmounted by a cap or cover, B. Said cap is milled upon its edgeandhas a squared projection, d, upon the top for the use of a wrench, when required` The body of the cup terminates in a. screw-stem or shank, C, which is intended to fasten or hold it in its proper position upon themachineto which it is attached. Said shank `C has a longitudinal hole drilled and tapped in the cen-tre of its body, of. a proper size to receive the spindle or plug a. At a point, e', this hole is diminished in diameter,

and is continueli of such diminished size till it peri'ora'tes the oil-chamber A. The junction of the smaller hole with the larger forms a shoulder at e, iig. 2. AThe spindle or plug a is a cylindrical piece of metal, (or other suitable materialghaving itstnpper end tapered or cone-shaped, The cylindrical portion is threaded, and is made of'su'ch relative size tothe hole in shank G (made for its reception) as to neatly it it. The upper or tapered portion enters' the-small hole or oil-passage, when the plug is in position as seen in 6g. 2, and can be made to abut against or recede from the shoulder e, as miay be desiredyby the use of a screwdriver in a slot made for its reception in the lower end of the plug, as seen at a. Said plug also hasl a hole or oil-passage, b, drilled in it from its lower end upward asuiiicient distance, so that a cross-hole made in the tapered portion at c `will intersect it, and thus form a continuous passage for the oil or other lubricating liquid. Another manner of providing saidpassage is simply to file away part of the body of the plug, which will answer the same purpose as drilling, and may be preferred, as,being'more easily done.

Having given a full description of our invention, the manner oi` operating is as follows: Before screwing the cup fast to the place it is desired to supply with oil, the oil-chamber should be iilled and the cap screwed on tightly, the spindle or-plug a having been prvio'uslyadjusted, so that its tapered part abuts againstthe shoulder e. This elosesth-e oil-passage and prevents the liow of oil. The plug a should then be slacked ofi` or turned away from said shoulder, so that the oil may be drawn out by suction, but will not How without. The cup is now regulated, and will not require further adjustment, unless oil of a diifcrent density is used.

Several important advantages are gained by this method of constructingroibcups. First, it is extremely simple, and is very cheaply and easily constructed; second, it has stood 'severe practical tests, and has proved very economical in consumption of oil, as itis automatic in its action, and will not feed when the machinery to which it is applied is not in motion. Another important advantage is that it can be easily repaired if accdenytally broken.

We do not'br'oadly claim the general application of a needle or spindle to an oil-cup, as we are aware that such, a device has already been applied to the cover or cap of an oil-cup, and made adjustable therefrom. Neither .do we claim an open tubelor pipe adjusting in the shank of an oil-cup. But what we do claim as new, of our invention, and desire to secure by Letters Patent of the United States, is-

'The peculiar combination and arrangement of the adjustable spindle or plug a with the shank C of an oiicup, constructed and operating substantially as described.
